IMPROVEMENT IN MEAT-CHOPPERS.

Specification forming part of Letters Patent No. 183,938, dated October31, 1876 application filed August 19, 1876.

To all whom it may concern Be it known that I, DAVID R. KINYON, ofRaritan, in the county of Somerset and State of New Jersey, haveinvented certain new and useful Improvements in Meat-Chopping Machines;and that the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theaccompanying drawings, making a part of this speciiication, in which-Figure l represents a perspective view of the machine. Fig. 2 representsa top View ot' the frame with the upper parts removed. Fig. 3 representsa vertical section of the same through the axis of the chopping-block.

Similar letters of reference Where they occur denote like parts of themachine in all the iigures.

My invention relates to machines for chopping meat, vegetables, &c., inwhich a slow rotary motion is transmitted to the block upon which thechopping is done, while a series of knives are raised and lowered aboveit, operating rapidly upon the meat to reduce it to ne and uniformparticles; and the object of my invention is to locate the center of theblock in relation to the center of the frame and knife-arm, upon oneside of it, so that 011e of the knives shall cut to the center of saidblock, thereby preventing clogging. lts object is also to construct theframe out of as few pieces as possible, to make it stronger and thefitting of the parts less expensive; and making the knife-arm adjustableand removable, it can readily be taken oft the machine to clean or renewthe chopping-block, and be replaced in position without removing anyother part of the machine.

To enable others skilled in the art to make and use my invention, I willproceed to describe the same with reference to the draw- 1n gs.

'lhe frame is cast in two pieces, the part A having formed upon it thevertical guideway a for the heel or guide c of the knife-arm C; theboxes al, to receive the main shaft d; the ears a2 and a3, to carrystuds for axis of revolving parts, as will be described hereafter 5 thesocket for one of the side bearings and for the central spindle e of thechoppingfblock E, and

one of the feet of the machine, all these parts being formed in onecasting. The part B of the frame has two feet, b, and the two socketsfor the side bearings b1 for the block E, and is connected to the part Aof the frame by two bolts, b2. The knife-arm C and its guide c are castin one piece, the guide c fitting the guide- Way a. on the main frame.The knife-arm is mounted upon a vertical power-rod, F, and the sidestrain upon it is relieved by the heel or guide c, bearing against theguideway a, formed upon the frame. This arm is made adjustable to thepower-rod F by means of a setscrew, g, so that it can be lowered bodilywith the knives G, as the block E becomes worn, or can be taken off thepower-rod and the block removed after the meat is cut. The knives Grreceive a reciprocating motion by means of the crank-pin h, projectingfrom the disk H, working into the slot-piece f, cast to the uprightpower-rod F, the rod being guided by two arms, c', bolted to the frameA. The block E is revolved slowly by means oi' an eccentric, k, castupon the hub of the fly-wheel K, operating upon the forked lever l,pivoted to the ear a3 of the frame, this forked lever operating upon alever, m, pivoted to the spindle e, and located horizontally beneath theblock E. The lever m carries a spring-pawl, n, that engages with theratchet-wheel E]l ot the block E, and receiving cylinder E2. The centerof the revolving block is not in a line with the center of theknife-arm, but so placed that one knife shall cut to the center of theblock, and the other as far from it as the knives are apart, so that themeat lying at the center ot' block always passes under one knife, andthe space at the side of the lirst-acting knife, between it and the rimof the block, is less wedging, thereby preventing clogging.

To operate with this machine, the meat or other substance is placedwithin the cylinder E2, and motion given to the gear-wheel M by means ofthe handle M', or otherwise. This gear-Wheel, rotating upon a studriveted to the ear a2 of the frame, transmits its motion to the pinionN, mounted upon the main shaft d, and through it to the dii'erent partsof the machine.

In small machines, for family use, I prefer to employ a single knife,operating upon the block at right angle with the knifearm G.

Having now described my invention, I claim- 1. The block E, located uponone side of a vertical longitudinal plane passing through the center of'the knife-arm, in combination with said knife-arm, carrying two knives,acting together substantially as and for the purpose described.

2. The knife-arm C and its extensionguide c, the gnideway a, boxes al,ears a2 and a3, and socket for spindle e, constructed and arranged asand for the purpose described.

3. In combination with the power-rod F and
